Reading and parsing a text file object
by egf05＠doc.ic.ac.uk 19 Jul '06

19 Jul '06

Hi, I am new to Zope (but familiar with Python) and have a question. I have a text file in a folder and I would like to parse its content, and I wanted to put the text in a string variable. I understand I can access the content through file.data or better str(file.data). However, the string I obtain has no carriage returns anymore, they are replaced by a space. This is annoying because I cannot split the file line by line. Is there a "trick" I do not know? Or is there a better way to parse the content of a text file object? Any advice would be very appreciated. Thanks, Eric

ExternalFile - getting back the file
by krokodylek＠tenbit.pl 19 Jul '06

19 Jul '06

Hi :-) I'm using the ExternalFile product: http://www.zope.org/Members/arielpartners/ExternalFile because I need to have a file both in ZMI, as well as in filesystem. I would like to ask if anyone can tell me how to get back the file that ExternalFile was created from, having only the object? In fact I do not need the file itself, but tha data (bytes) that were inside. I would be very grateful for any help. Best regards, Maciej Zieba

Using the DTML REQUEST Object
by Muk Yan 19 Jul '06

19 Jul '06

Dear Exalted Sirs and Madams, I'm a Zope newbie, so be gentle. I'm using DTML on Zope (yes I know Plone and Tal is now the norm) and I was wondering if regularly using the REQUEST(set and get) object is bad practice. I'm mostly a C++ programmer and I know of the horrors of global variables, but I was wondering if there was any way to pass information from DTML Documents to DTML Methods and vice versa (and maybe from DTML Methods to DTML Methods) without using the REQUEST object. Thanks and take care, Muk Yan

Re: [Zope] external method with import tarfile

Hi there! I managed to find the problem and the solution. First, I've forgot to mention that in my script, oname is an uploaded file. I just inserted a f.close() and voilá! def upload_external(self,file,REQUEST): import os,tarfile ... f=open(oname,"wb") f.write(file.read()) f.close() ... tar = tarfile.open(oname,"r:gz") for itar in tar: tar.extract(itar.name,jobdir) return "Done" Cheers, Alan On 18/07/06, Alan <alanwilter(a)gmail.com> wrote: > Thanks for your reply. > > Yes, my script works and my file are not broken.

question on simple_send in MailHost
by John Schinnerer 19 Jul '06

19 Jul '06

Aloha, The Zope (2.7.5) API docs for MailHost show this for simple_send: -------------- simple_send(self, mto, mfrom, subject, body): Sends a message. Only To:, From: and Subject: headers can be set. The arguments are: mto A commaseparated string or list of recipient(s) of the message. mfrom The address of the message sender. subject The subject of the message. body The body of the message. -------------- So it reads like it can handle more than one To: address, something like this comma-separated string: 'me@mine.com,you@yours.com,him@his.com' ...but when I do this the message only gets sent to the first address in the list. Is this a mistake in the docs - do I need to use send() to send to multiple addresses? Or is there something wrong with my comma-separated string of recipients? Or is there a third possibility I haven't even considered... :-) thanks, John S. -- John Schinnerer - MA, Whole Systems Design ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john(a)eco-living.net http://eco-living.net

ZSQL Method Question
by Benjamin Menking 19 Jul '06

19 Jul '06

New to python/Zope, old-timer on PHP.... I'm using MySQL and a ZSQL method to insert data into the database. ex: insert into org (org_name, org_phone) values ('x', 'y') What I'm trying to figure out is that org_id (also part of the org table, but not specified in the sql statement) is an auto_increment primary key field and in PHP I can use mysql_insert_id() to find out what org_id was set to after the mysql_query() call. Is there a way to retrieve that value with ZSQL method, or must I use some other mechanism? Thanks! -- Ben Menking RHCE IT Security Consulting (864) 420-5603 (864) 751-1638 fax IT and Business Solutions

external method with import tarfile
by Alan 18 Jul '06

18 Jul '06

Hi! I am trying to run a external python script. Now I am facing a problem that occurs only when I run the script via Zope. ... import os,tarfile ... tar = tarfile.open(oname,"r:gz") for itar in tar: tar.extract(itar.name,jobdir) gives me: Site Error An error was encountered while publishing this resource. Error Type: IOError Error Value: CRC check failed If I comment the for loop my scripts finish well, but then it does not uncompress the file. Please, any help would very appreciated. Many thanks in advance, Cheers, Alan -- Alan Wilter S. da Silva, D.Sc. - Research Associate Department of Biochemistry, University of Cambridge. 80 Tennis Court Road, Cambridge CB2 1GA, UK. >>http://www.bio.cam.ac.uk/~awd28<<

Problem with ZEO connection - DisconnectedError
by krokodylek＠tenbit.pl 18 Jul '06

18 Jul '06

Hi :) My site was running fine with Zope-2.7.4 and ZEO when all of a sudden on some (!) of the pages I've started getting "DisconnectedError". This hasn't happened before and I didn't change anything in my configuration... I've checked the zeo-server's log, here is the important entry: 2006-07-17T13:58:46 ERROR(200) zrpc-conn:172.16.0.43:54825 Error caught in asyncore Traceback (most recent call last): File "/home/zope/usr/lib/python/ThreadedAsync/LoopCallback.py", line 120, in poll obj.handle_read_event() File "/usr/lib/python2.3/asyncore.py", line 390, in handle_read_event self.handle_read() File "/home/zope/usr/lib/python/ZEO/zrpc/smac.py", line 217, in handle_read self.message_input(msg) File "/home/zope/usr/lib/python/ZEO/zrpc/connection.py", line 225, in recv_handshake raise ZRPCError("bad handshake %r" % proto) ZRPCError: bad handshake '(K\x00K\x00U\x0fgetAuthProtocol)t.' I really have no idea what's happening :-O I've searched the Internet and the only thing I could found is this news (see: What's new in ZODB3 3.2.6b1? ZEO): http://www.zope.org/Products/ZODB3.2/NEWS Could I be a victim of this bug? It seems strange that this only happens on some of the pages... If so - Zope-2.7.4 has to have an old ZODB version, how do I safely upgrade it? This is a production server, I really can't loose any data :-( Maybe this is important - ZEO server and ZEO client are not on the same machine, they're connected with network. Or is it something else? Can anyone please help me? I'm glad to give you more information if needed :-) I wanted to send this message to ZODB-Dev but I can't seem to register nor send mails there... Best regards, Crocodil
